Can this code be sped up?

In a website I’m designing I use this code to move from page to page, but on slower computers it tends to take ages & cause lots of strain on the processor. I’m Actionscript genius so please could the answer be spelled (or typed…) out - I’ve heard, but not sure if it’s true, that there is a more efficient way than onEnterFrame, please correct me if I’m wrong. Is there an alternative to this? I would really appreciate any and all help.

_global.targetX = 0;
_global.targetY = 0;
initWindow();
window_mc.container_mc.onEnterFrame = moveCamera;
function initWindow() {
        var c = 0;
        for (i=1; i<11; i++) {
                myClip = _root.window_mc.container_mc["clip"+i];
                if (i%2>0) {
                        myClip._x = 0;
                        myClip._y = c*552;
                        c++;
                } else {
                        myClip._x = 900;
                        myClip._y = _root.window_mc.container_mc["clip"+(i-1)]._y;
                }
        }
}
function moveCamera() {
        friction = 0.1;
        distanceX = (targetX-this._x)*friction;
        distanceY = (targetY-this._y)*friction;
        this._x += distanceX;
        this._y += distanceY;
}
function updateTargets(x, y) {
        targetX = x;
        targetY = y;
}

Cheers in advance,
